Now that you are in UK, there is little point in knowing the Mahadasa Antardasa based on Sharjah birth since you are now governed by longitude/latitude of planets based on transit horoscope at London. You can contact us through Paid consultation after reading through my book given in my profile.

The Dasas and apaharams are dependent on the place where you are now resident and there is little point in doing such evaluation based on the place of birth. And to do so takes quite a lot of time and you cannot get free answers to such questions. However Sun Mahadasa will be fairly strong while Moon is quite a weak malefic.
